Effect of Reserpine on Plasma Prolactin, Growth Hormone and Thyrotropin in Dairy Heifers

In May and October, the effect of reserpine on releases of prolactin (PRL), growth hormone (GH), and thyrotropin (TSH) was studied in Holstein dairy heifers. In May, an intramuscular injection of 6μg reserpine per kg body weight (bw) caused a marked and prolonged elevation of plasma PRL level. The p...

Zusammenfassung:In May and October, the effect of reserpine on releases of prolactin (PRL), growth hormone (GH), and thyrotropin (TSH) was studied in Holstein dairy heifers. In May, an intramuscular injection of 6μg reserpine per kg body weight (bw) caused a marked and prolonged elevation of plasma PRL level. The peak PRL level at 2.5hr post-injection was 15.6 times as high as pre-injection level (P
